Moving around between different machines I sometimes run into Lazarus giving me warnings like these:
ld: warning: object file (/Volumes/GoogleDrive/My Drive/Projects/LazarusProjects/Tests/Test GetMntInfo/lib/aarch64-darwin/project1.o) was built for newer macOS version (11.0) than being linked (10.8) ld: warning: object file (/Users/hans/fpcupdeluxe/fpc/units/aarch64-darwin/rtl/system.o) was built for newer macOS version (11.0) than being linked (10.8) ld: warning: object file (/Users/hans/fpcupdeluxe/fpc/units/aarch64-darwin/rtl/lnfodwrf.o) was built for newer macOS version (11.0) than being linked (10.8) ld: warning: object file (/Users/hans/fpcupdeluxe/fpc/units/aarch64-darwin/rtl/exeinfo.o) was built for newer macOS version (11.0) than being linked (10.8) ld: warning: object file (/Users/hans/fpcupdeluxe/fpc/units/aarch64-darwin/rtl/strings.o) was built for newer macOS version (11.0) than being linked (10.8)
Basically saying, in this example, that an object file was build for one macOS version, yet linked against a different version.
I will not claim to be an expert, but this is how I usually fix this:
In Lazarus goes to Project - Project Options - Compiler Options - Custom Options.
In the field "Custom options", we need to at the"-WM" option which allows us to select a specific SDK.
For example: -WM12.0 will enforce the macOS 12.0 SDK.
Now do a "Clean and Build" for you project and things should be OK now.
Alternatively, I read you can add this to the fpc.cfg file as well.
Note that this trick becomes even more relevant with Sonoma, where SDK 10.9 is a minimum requirement to notarize your Lazarus applications.
This would be the error: The binary uses an SDK older than the 10.9 SDK.
You can find the error with
xcrun notarytool log --apple-id "email" --password "pwd" --team-id "teamid" UUID
where the info is based on what you used to submit the app for notarizing:
So this could look something like this:
xcrun notarytool log --apple-id "email@example.com" --password "abgf-yuhg-zzsd-abcd" --team-id "X9F96M8JH7" 5bd49972-666f-4f80-87bc-7f8f81c62206
The JSON formatted result will look something like this:

p.s. I typically use "-WM11.0"
